A novel facultatively anaerobic, non-spore-forming, non-motile, catalase- and oxidase-positive, Gram-negative and rod-shaped bacterial strain, designated Y12T, was isolated from activated sludge of a wastewater bio-treatment facility. The strain was able to degrade about 90 % of added propanil (100 mg l−1) within 3 days of incubation. Growth occurred in the presence of 0–4.5 % (w/v) NaCl (optimum 0.5 %), at 10–40 °C (optimum 28 °C) and at pH 5.5–10.0 (optimum pH 7.0). Vesicular internal membrane structures and photoheterotrophic growth were not observed. The major respiratory quinone was ubiquinone-10 and the major cellular fatty acid was summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The genomic DNA G+C content of strain Y12T was 63.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain Y12T was a member of the genus Catellibacterium, as it showed highest sequence similarities to Catellibacterium caeni DCA-1T (99.1 %) and <96.0 % similarities with other species of the genus Catellibacterium. Strain Y12T showed low DNA–DNA relatedness values with C. caeni DCA-1T. Based on phenotypic, genotypic and phylogenetic properties, strain Y12T represents a novel species of the genus Catellibacterium, for which the name Catellibacterium nanjingense sp. nov. is proposed. The type strain is Y12T ( = CCTCC AB 2010218T  = KCTC 23298T). An emended description of the genus Catellibacterium is also presented.

Phototrophic Growth

A bacterial strain, designated AST4T, was isolated from activated sludge. The bacterium did not show significant growth on nutrient broth, but growth was clearly stimulated by addition of supernatant from other bacterial cultures. Culture filtrate of a strain related to the genus Sphingomonas in particular increased the cell yield and growth rate of strain AST4T. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain AST4T is located within the ‘Rhodobacter group’ in the α-3 subclass of Proteobacteria, but is clearly distant from related genera in this group such as Paracoccus, Rhodobacter and Rhodovulum. Strain AST4T is a Gram-negative, non-motile, rod-shaped (0·6–0·8×1·3–2·0 μm) and aerobic bacterium. It was not able to reduce nitrate to nitrite or N2. No phototrophic growth was observed. Optimal growth occurred at 30 °C and pH 6·5–7·5. The dominant cellular fatty acid in the isolate was C18 : 1 cis11. Ubiquinone-10 was the major respiratory quinone. The G+C content was 64·5 mol% (by HPLC). Based on the phylogenetic and phenotypic traits, the name Catellibacterium nectariphilum gen. nov., sp. nov. is proposed for this isolate; the type strain is AST4T (=NBRC 100046T=JCM 11959T=DSM 15620T).

A bacterial strain, designated V2M29T, was isolated from forest soil collected in the Changbai Mountains, Heilongjiang Province, China. Cells of strain V2M29T were Gram-positive, rod-shaped (0.5–0.8 μm in diameter and 1.5–2.0 μm in length), strictly aerobic and non-motile. Colonies produced on R2A agar plates were creamy, smooth, circular and 0.3–0.8 mm in diameter. Strain V2M29T grew at 14–35 °C (optimum, 29 °C), at pH 4.1–10.0 (optimum, pH 7.0–8.0) and in the presence of 0–7.0 % (w/v) NaCl (optimum, 0–2.0 %). Strain V2M29T contained MK-8(H4) as the major respiratory quinone and iso-C15 : 0 (20.9 %), iso-C16 : 0 (18.5 %), C17 : 1 ω8c (16.7 %) and 10-methyl-C17 : 0 (9.2 %) as the major cellular fatty acids. The cell-wall peptidoglycan type was based on meso-2,6-diaminopimelic acid and the acyl type of the muramic acid was acetyl. Diphosphatidylglycerol, phosphatidylinositol and six unknown glycolipids were the major polar lipids. The G+C content of the DNA was 72.0 mol% (T m). 16S rRNA gene sequence analysis indicated that strain V2M29T was phylogenetically related to members of the genus Phycicoccus, with sequence similarities ranging from 96.6–97.8 %. The DNA–DNA relatedness values of strain V2M29T to Phycicoccus dokdonensis DS-8T and Phycicoccus bigeumensis DSM 19264T were 32.5±3.3 % and 29.2±2.3 %, respectively. Based on these results, it is concluded that strain V2M29T represents a novel species of the genus Phycicoccus, for which the name Phycicoccus cremeus sp. nov. is proposed, with V2M29T (=CGMCC 1.6963T =NBRC 104261T) as the type strain.

A novel Gram-reaction-negative, aerobic, pale-orange-pigmented bacterium, designated strain SM1216T, was isolated from Arctic intertidal sand. Cells of strain SM1216T were dimorphic rods with a single polar prostheca or flagellum. The strain grew at 4 − 30 °C (optimum at 25 °C) and with 0.5 − 6 % (w/v) NaCl (optimum with 2 − 3 %). It reduced nitrate to nitrite but did not hydrolyse gelatin, DNA or Tween 80. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SM1216T was affiliated with the genus Algimonas in the family Hyphomonadaceae, sharing 97.5 and 96.3 % similarity with Algimonas ampicilliniresistens 14A-2-7T and Algimonas porphyrae 0C-2-2T, respectively, the two known species in the genus Algimonas. However, the level of DNA–DNA relatedness between strain SM1216T and the type strain of A. ampicilliniresistens, the nearest phylogenetic neighbour, was 57.9 %. The major cellular fatty acids of strain SM1216T were C18 : 1ω7c and C18 : 1 2-OH. The main polar lipids of strain SM1216T were monoglycosyldiglyceride (MGDG), glucuronopyranosyldiglyceride (GUDG), phosphatidylglycerol (PG) and three unidentified phospholipids (PL1–3). The major respiratory quinone was ubiquinone 10 (Q10). The genomic G+C content of strain SM1216T was 60.6 mol%. On the basis of the evidence from this polyphasic study, strain SM1216T represents a novel species in the genus Algimonas, for which the name Algimonas arctica sp. nov. is proposed. The type strain is SM1216T ( = MCCC 1K00233T = KCTC 32513T). An emended description of the genus Algimonas is also given.
